Application filed April 22,

To all whom it may concern: Be. it known that I, CHARLES H. GAIL, acitizen of the United States, residing at Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in Bed-Springs, of which the following is a specification.V

V The present invention is designed to provide simple and efficientmeans "for yieldingly securing together the top coils or convolutions ofthe upright spiral springs of bed-springs and similar structures,whereby the bed-spring or other structure as a whole will'possess markedresilient or cushioning capabilities.

It is not broadly new to fasten the upper coils of such spiral springstogether by means of short helical or coiled springs, but one leadingpurpose of the present invention is the fastening or securing o'ftheends of such intermediate or connecting helical springs to the uppercoils of the vertical spiral springs in such manner that they cannotshift position under ordinary usage, that the. structure will be whollynoiseless, and that the top coils will not need to be crimped ordeformed to hold the helical springs. firmly in place.

A further purpose of the invention is the production or provision of anappliance of this kind having a relatively smooth flat top surface soconstructed that the superposed mattress will not sag or be depressed unI duly into or between the several springs of which the structure iscomposed.

In its preferred embodiment, the inven-' tion takes the form ofstructure illustrated in the accompanying drawing in the two views ofwhich like reference characters have been used to designate the sameparts.

In this drawing:

Figure 1 is a fragmentary or partial plan view of a small portion onlyof the complete cushion spring but suiiicient of the construction hasbeen shown. for the needs of this patent application; and

Fig. 2 is an enlarged cross-section on line 2-2 of Fig. 1, the partsbeing viewed in the direction indicated by the arrows.

The improved and novel bed-spring, the principles of construction ofwhich may be advantageously employed in many other relations wherecushion structures of this general type are desired, comprises, as willbe readily seen from the drawing, a plurality Specification of LettersPatent.

of suitably-supported, vertical, aced spiral shown.

It 1s, of course, necessary toitie or secure these top coils together toInaintainf the springs at all times in propejrposition nd this ispreferably done by" employing elastic or expansible and contractiblehelical springs arranged horizontally between such upper-' most coils,thus giving the latter adequate manent displacement.

To this end, the upper coil of each spiral spring, except the marginalor border ones;-

not illustrated, is connected to thecorre-f sponding coils of the fouradj acent springs by that number of horizontal, helical springs; 12,13,- 14 and 15 arranged ninety degrees apart with the springs 12and'lidiametrifreedom of movement Without undue or percally opposite oneanother and the remaining springs 13 and 15 similarly disposed;

The loops 16 ofthe springs 12 and 14,

formed by properly bending the end portions of the wires of which'thesprings are made,

project inwardly over and rest on the wire forming the top coil of thespiral spring under consideration, and such loops or eyes] are-securelyfastened 1n position by a cross-.

wire 17 eixtendedacross themiddle of the top coll, each end'being bentto pass; down through the loop at 1 8 inside of the top coil, I

then outwardly at 19 beneath the wire constituting such top coil, thenupwardly at 20 through the loop outside of. the top coil, then over oneside of the loop at 21,. and then down over the side of such portion ofthe loop. at 22.

By this simple means, these ends of the two oppositely-disposed springsare so Se:

curely and firmly fastened to the spiralsp-ring that unintentionaldislodgment or displacement is impossible even though the wire formingthe top coil is not crimped at these points of attachment.

It will be observed that the end of eachv helical spring is heldsecurely against the.

upwardly-extended part 20 of the fastening wire and that the latter isfirmly held against v t the outer side of the top coil by reason of thesection 18 of the wire which bears againstv the end of the loop, wherebythe loop 1s very same spiral-spring by means of similarly bent ends ofanother Wire 23 crossing such top coil at right angles to and eitherabove or below the wire 3.

The other ends oi each of these four helical springs are in like fashionsecured to the coils of the four adjoining or neighboringspiral-springs, it being understood that each ofthe latter is connectedto four other springs in the manner indicated.

The crossing wires 1? and 23 of each up right spring not only affordmeans for securing or tying the helical springs in position but theyalso act as mattress supporting means preventing the mattress fromunduly sagging into the spring.

'The improved and novel structure illustrated and described affords adesirable cushion or bed-spring with suitable resilient and elasticcapabilities and functions,

' which is comparatively simple in structure,

the elements of which may be quickly and readily placed in position andassembled, and which is free from noise when 1n use,

the helical springs being so immovably clamped. to the spiral-springsthat slipping or sliding out of place is out of the question.

Many minor mechanical changes may be incorporated in the, constructiondetailed above and still the latter would embody the invention aspresented in the appended claims, because the invention is susceptibleof embodiment in a variety of forms all containing the'i undamentalprinciples of structure and function on which the invention rests.

'1. In a bed-spring, the combination of an upright spiral-spring, ahorizontal helicalspring having an end loop overlying the top coil ofsaid spiral-spring, and a wire having a portion bent down through saidloop inside of said top coil, then passing beneath the wire forming saidtop coil, then extending upwardly through said loop, then over the topof one side of said loop, and then down over the side of the loop.

In a bed-spring, the combination of an upright spiral-spring, ahorizontal helicalspring having an end loop overlying the top coil ofsaid spiral-spring, and a Wire extended across said top coil and havinga portion bent down through said loop inside of said top coil, thenpassing beneath the wire forming said top coil, then extending upwardlythrough said loop outside of SELlCl top coil, then over the top of oneside of said loop, and then down over the side of said side of theloop.
